Completed

• Conditions: MPS - Mucopolysaccharidosis; Morquio Disease
• Interventions: Other: Interview

• Registration Number: NCT03150069
• Lead Sponsor: Emory University

Brief Summary

The present study seeks to interview women with Morquio A and Morquio B syndrome, to explore their concerns surrounding pregnancy and the impact of ERT on their perspectives, in comparison with the control group of Morquio B subjects for whom no ERT treatment exists.

Interviews will be conducted by a health psychologist, in-person or over the telephone. Data will be analyzed using MAXQDA 12.0 software and Grounded Theory. Differences in thematic trends between Morquio A subjects, for whom treatment exists, and a control group of Morquio B subjects, for whom there is no treatment, will be compared.

Detailed Description

The present study seeks to interview women with Morquio A and Morquio B syndrome themselves, to explore and discover their perspectives and concerns surrounding pregnancy and having biological children, the impact of the advent of ERT for Morquio A on their perspectives and concerns in comparison with the control group of Morquio B subjects for whom no ERT treatment exists, as well as what each group is being told by the medical community and others in their lives in this regard.

Interviews will be conducted by a health psychologist, either in-person or over the telephone. We will interview 1) those women with Morquio syndrome who are known to have been pregnant and 2) those women with Morquio syndrome who have not been pregnant and/or chose to adopt children. All information will be kept confidential, except as in accordance with Georgia law relating to reporting of child or elder abuse, suicidal and/or homicidal intent.

Data will be analyzed using MAXQDA 12.0 software to develop code which can be used to describe and compare the data using Grounded Theory. Differences in thematic trends between Morquio A subjects, for whom treatment exists, and a control group of Morquio B subjects, for whom there is no treatment, will be compared.
